Test 2 is on Friday October 24. It will cover: 10.4, 10.5, & 11.1 - 11.7. Integrals from any section may come up in the integral test or with polar coordinates problems. There will be one proof; it will be either the geometric series formula ([4] page 706), the p-series test ([1] page 716), or the first Comparison Test (page 722).
